I have to admit guys, that BB2 is the only game, out the 3 I play most (BB, BB2 and PI), which shouldn't have more than 1 'difficulty' categories (other than kids of course). I struggled many times, when playing a level, to identify which category it should be in (without looking the pre-set one from the editor) and I realized that either most of the levels are not properly categorized or because there was something more simple, that all levels should belong to one category [whatever that is]. Not that it makes any difference but I just wanted to share my thoughts. P.S. We could also exclude 'Big Maps' as a category in the sense that these levels do not actually relate to difficulty but rather a big challenge with more moves.
